CE Standards Machinery Directive

EN 349:1993+A1:2008

Safety of machinery – Minimum gaps to avoid crushing of parts of the human body

The object of this European Standard is to enable the user (e.g. standard makers, designers of machinery) to avoid hazards from crushing zones. It specifies minimum gaps relative to parts of the human body and is applicable when adequate safety can be achieved by this method. This European Standard is applicable to risks from crushing hazards only and is not applicable to other possible hazards, e.g. impact, shearing, drawing-in.

EN 1088:1995+A2:2008

Safety of machinery – Interlocking devices associated with guards – Principles for design and selection

This standard specifies principles for the design and selection – independent of the nature of the energy source – of interlocking devices associated with guards (as defined in 3.23.1 “interlocking device (interlock)”, 3.22.4 “interlocking guard” and 3.22.5 “interlocking guard witg guard locking” of EN 292-1:1991). It also provides requirements specifically intended for electrical interlocking devices. This standard covers the parts of guards which actuate interlocking devices. Requirements for guards are given in prEN 953. The processing of the signal from the interlocking device to stop and immobilize the machine is dealt with in prEN 954-1.

EN 953:1997

Safety of machinery – Guards – General requirements for the design and construction of fixed and movable guards

This European Standard specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards. The standard applies primarily to machines which are manufactured after the date of issue of this standard. Attention is drawn to the use of guards to minimise exposure to non-mechanical hazards. The requirements are applicable if fixed and movable guards are used. The standard does not cover those parts of guards which actuate interlocking devices. These are covered in EN 1088. This standard does not provide requirements for special systems relating specifically to mobility and ability to lift loads like rollover protective structures (ROPS) and falling-object protective structures (FOPS).

Includes the Amendment 1 of 2009.

EN-ISO 13849-2:2008

Safety of machinery – Safety-related parts of control systems – Part 2: Validation

This European Standard specifies the procedures and conditions to be followed for the validation by analysis and testing of:
– the safety functions provided, and
– the category achieved of the safety-related parts of the control system in compliance with EN 954-1 (ISO 13849-1), using the design rationale provided by the designer.

EN-ISO 13849-1:2008

Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design

This part of ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety- related parts of control systems (SRP/CS), including the desig n of software. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carry ing out safety functions. It applies to SRP/CS, regardless of the type of technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.), for all kinds of machinery.

EN-IEC 60204-1:2006

Safety of machinery – Electrical equipment of machines – Part 1: General requirements

This part of IEC 60204 applies to the application of electrical, electronic and programmable electronic equipment and systems to machines not portable by hand while working, including a group of machines working together in a co-ordinated manner. The equipment covered by this part of IEC 60204 commences at the point of connection of the supply to the electrical equipment of the machine (see 5.1). This part of IEC 60204 is applicable to the electrical equipment or parts of the electrical equipment that operate with nominal supply voltages not exceeding 1 000 V for alternating current (a.c.) and not exceeding 1 500 V for direct current (d.c.), and with nominal supply frequencies not exceeding 200 Hz. This part of IEC 60204 does not cover all the requirements (for example guarding, interlocking, or control) that are needed or required by other standards or regulations in order to protect persons from hazards other than electrical hazards. Each type of machine has unique requirements to be accommodated to provide adequate safety. This part specifically includes, but is not limited to, the electrical equipment of machines as defined in 3.35.
